  • Through deriving the matrix representations of the critical-sampled Filtered Multi-Tone(FMT) modulation system, a new subchannel frequency-domain equalization algorithm is proposed in this paper to eliminate the Inter-Symbol Interference(ISI) in critical-sampled FMT system. The coefficients of the equalizer are calculated based on Maximizing Subchannel Bit-rate(MSB) rule. Simulation results show that the ABR performance of the proposed algorithm is enhanced 40 percent and 70 percent respectively in comparison with that of the previously proposed frequency domain equalization algorithm based on minimum-mean-square-error rule(LIN) and the DFE equalization algorithm, and the proposed algorithm brings about 3 dB and 5 dB improvement over the LIN and the DFE equalization algorithm in ATTC E channel; in the WLAN Channel, the ABR performance of the proposed algorithm is enhanced 45 percent and 75 percent respectively in comparison with that of the LIN and the DFE equalization algorithm, and the proposed algorithm brings about 6 dB and 10 dB improvement over the LIN and the DFE equalization algorithm.
